IPC: G08B13/24
Filed: 1990-06-04
Abstract: A method of deactivating a frequency-dividing-transponder (10) that includes an active strip (12, 14) of magnetic material that, when magnetically biased to be within a predetermined magnetic field intensity range, responds to excitation by electromagnetic radiation of a first predetermined frequency by radiating electromagnetic radiation of a second predetermined frequency that is a frequency-divided quotient of the first predetermined frequency; and a magnetized bias strip (16) of magnetic material having first and second ends and disposed in relation to the active strip of magnetic material for magnetically biasing the active strip of magnetic material to be within the predetermined magnetic field intensity range only when the bias strip of magnetic material is magnetized. The method includes the step of converting the bias strip of magnetic material into a tripole bar magnet, having a pole of one magnetic polarity in a predetermined region of the strip (16) located between the ends of the strip (16), and having a pole of a different magnetic polarity than the one magnetic polarity at each end of the bias strip (16) to thereby provide opposing magnetic bias fields in opposite longitudinal halves of the active strip (12, 14) for causing any electromagnetic radiation of the second predetermined frequency that is generated in one half of the active strip to be of equal and opposite polarity and thus cancelled by any electromagnetic radiation of the second predetermined frequency that is generated in the other half of the active strip. This is accomplished by laterally passing a magnet (32) across and in close proximity to the bias strip (16) of magnetic material, with the magnet having sufficient flux density to overcome the magnetic bias of the bias strip, and with the magnet being passed across the predetermined region of the bias strip.

Title: A method of desulphurizing hot waste gas
Inventor: RASMUSSEN STIG
IPC: B01D53/50
Filed: 1990-07-12
Abstract: A desulphurization process in which acid com­ponents of waste gas are removed by spray drying ab­sorption, using an aqueous suspension of slaked lime or limestone as absorbent with recycling of part of the reaction product is controlled on the basis of deter­minations of the chloride content of said aqueous sus­pension including recycled reaction product. Said determination is used for (a) controlling the amount of chloride in the aqueous suspension to such a value that a specific chloride content selected between 1 and 7% by weight, dependent on the difference between the tem­perature of the desulphurized waste gas and the adiabatic saturation temperature thereof, is obtained in the powdered product resulting from the spray drying absorption, and/or (b) for controlling the quantity of water evaporated by the spray drying, thereby changing in dependence on said chloride content the difference between the temperature of the desulphurized waste gas and the adiabatic saturation temperture thereof, within the limits specified under item a) and thereby increasing said difference when the chloride content of the suspension increases.

Abstract: There are disclosed a method and apparatus by which a calibration gas containing a controlled, very low concentration of a highly-adsorbent material (e.g. water) at a ppb level or below can be rapidly prepared with a precise concentration. The first stage of the dilution is described as follows: a large quantity L 1  of gas is supplied, and part L 2  of the gas is exhausted, and then a dilution gas L 3  is supplied to the gas. The pressure and flow rate of the gas are controlled by gas regulators (3,23) and flow controllers (4, 25), and impurities are removed from the gas by impurity removal devices (5, 29). The second stage operates analogous. Gas is introduced into a device (6) for producing a standard gas containing a high concentration of the sample (7). The so-prepared standard gas is introduced in a two-stage gas dilution system with a main tube (12) which is maintained by heating means (31) at a temperature 20 to 50 C higher than the boiling point of the liquid sample (7), thereby promoting the establishment of an equilibrium between the adsorption and desorption of the sample.
